BOYS STILT.

SPECIFICATION forming part of Letters Patent No. 241,226, dated May 10, 1881.

Application tiled May 15, 1880. (No model.)

To all tc/Lom it may concern: v

Be it known that I, HENRY LANDrs, M. D., ofthe city of Beading, county of Berks, State ot' Pennsylvania, have invented a new and useful Improvement in Boys7 Stilts, ot' which the following is a specification.

This improvement relates more particularly to stilts provided with a base or pedestal, by which the action is steadied and greater safety insured.

Referring to the drawings, in which similar letters refer to similar parts, Figure lis an inside elevation ot' the right-leg stilt. Fig. 2 is an outside elevation of the left-leg stilt. Fi 3 is a front elevation ot' the stilt, showing more clearly the suspension ot' the foot-rest. Fig. 4 is an enlarged elevation of the pedestal, showing mortise for rod C and ears for rod K.

A represents a semicircular longitudinal piece, of either wood or metal, provided with straps A A, by which it is secured to the leg of the user.

B is an extension-piece, of either flat iron or of a tube, the upperend of which is secured by bolts, rivets, or welding to the leg-piece A. C is a corresponding extension-piece, brought u p from the pedestal or base H ot' the stilt. B and C, it' of lat iron, are kept together, orseparated within detined limits, by distance-holes in each, in combination with a loose sleeve or pin. Iftubular,0 slides within B, and is kept at any desired point by screwed pin or pinching-screw B', passing through both rods or pressing against C.

D is ajoint or fulcrum pin for the arm D of the foot-rest D which has toe and heel pieces, similar to those ot' a skate, for the purpose of retaining the foot in place upon the foot-rest D. Thejoint or fulcrunl pin D is placed above the sole ot' the foot-rest, at a point correspondin gwith the height of the ankle-joint above the Sole ofthe foot. The foot-rest D".has ears and joint-piu E at the heel, for connection with the secondary rods J K, which pair-ot' rods may, like B and C, be either hat or tubular, and secured in a similar manner by pin or pinching.

screw J.

H is the pedestal, having a mortise and pin, F, for the head of the rod C, and ears and pin G at the heel for the head of the rod K.

h is a rubber sole applied to the pedestal to of dams and hydraulic works would find them adapted to their use. Fishermen and schoolchildren could mutually enjoy the immunity secured by their use' from muddy roads and wet banks.

It will be seen that I introduce a full support for the foot by the rest D, and, securing the lower limb to the stilts by the straps A A, the ankle is left free in its movement. The joint D of the foot-rest is coincident with the joint of the ankle. rlhejoint E at the heel of the foot-rest transfers all the walking movement of the foot through the rods J K to the base H, which, being loosely attached to the rods` B C, partakes ot' lthe motion of the footrest, and thus, as it were, places the wearer of 8o the stilt with his feet upon the ground, without any reference to the height to which in reality he is above it.

For the purpose of making the stride ofthe stilt elastic I place upon the sole ot' the pedestal H a layer ot india-rubber, h, or some equivalent therefor. rIhis will relieve the usual jar attendant upon the use of the ordinary stilt.

I am aware that adjustable stilts, and stilts having compound feet connected so as t0 have a movement relative to each other, are not new, (see patents to V. Jordan, No. 76,465, April 7, 1868; to L. Brodervvick, No. 208,782, April 23, 1878; and I. F. Schultheiser, No. 218,457, August 12, 1879;) also, that rubber has been used for the purpose of lessening shocks and reducing the eiiect ot' sudden impact by the attachment to the end of a crutch or stilt, in the latter case shown but not claimed in Patent No. 207,782, April 23, 1878, to L. Broderwiek. I therefore do not broadly claim an adjustable stilt, a com pound-,toot stilt, nor arub- IOO ber-cushioned foot or pedestal, when used for the purpose shown and described.

I claim- 1. Astilthaving compound feet, in wl1iol1,by the combination of leg-piece A, rods B C and J K with joint-pins E, F, and G, swinging foot-rest D and pedestal H, and pinchingscrews B J', the stilt is adapted to be adjusted for vertical height of foot-rest Dl above the pedestal H, substantially as shown, and for the purpose described.

2. The foot-rest D, with a-rin D', when suspended from the leg-piece A by the fnlerumpin D, and provided at the heel with ears and joint-pin E, and so arranged that by the combination of the rods J K with the heel of the rest D and heel of the pedestal H, and by extension-rod C of leg-piece A, and fulcrum or joint pin F of pedestal H, the oscillating motion of the foot of the user, when placed upon the rest D, is transferred to the pedestal H, substantially as shown, and for the purpose described.
